GR21 ALL ROAD CARBON WHEEL 650B BLACK
The ROLLCii GR21 650B Carbon Wheelset is designed for riders who want the lively ride feel of a lightweight carbon wheelset while maintaining the versatility needed for gravel riding, mixed-surface adventures, bikepacking, and everyday exploration.
Built around a lightweight carbon rim with a 22mm internal width, the GR21 provides excellent support for modern gravel, all-road, and ATB tire sizes. The wider rim profile helps create a stable tire shape with predictable handling and improved comfort across changing terrain, from rough pavement to loose gravel and forest roads.
With a lightweight 28-hole 2-cross wheel structure and tubeless-ready construction, the GR21 balances rolling efficiency, durability, and everyday practicality. Whether paired with a gravel race bike, a steel all-road build, or a long-distance adventure setup, it is designed to deliver a responsive ride feel without sacrificing comfort or reliability over extended mileage.
